To all whom it may concern,.- V

Be it known ythat I, ARTHUR J. WEsT, residing in Milwaukee,. inthe county of Milwaukee and State of Wisconsin, have invented 'a new and useful Improvement in Oil'- Pump Motors, 'of which thefollowing is a descr1ption, reference bein had to the accompanying drawing, whic is a part of this specification.

This invention relates particularly to certain new and useful im rovements in oilpump motors, but broad y covers im Irovements in motors for any'purpose, and as for its ob'ect to provide operating means havin Inova le support from a moving body .an capable of imparting motion to an operated means b reason of the diHerence in the effect ro uced by the movements of the body on t e support and on the operating means, such difference, in effect, being due to the inertia of the operating means. Another object of this invention is to provide a moving body carrying an actuating means mounted to be movab e with relation to the moving body and means connecting the body and the said actuating means ada ted to receive motion as the result ofthe 1nertia of the actuating means during the movements of the body.

Another object of this invention is to rovide a machine oil-feed pump or the. ike with an automatic operating means adaptedv to impart motion to such oil-feed pum o1'V similar device during the movements o the machine only and receiving its impulse from vsuch movements of the machine.

A further objectof this invention is to accomplish the above results by means of a movable Weight, the inertia of whichV renders it less susce tlble to .the influence of the movements of t e machine than its sup ort and the difference in the -effects produce by such movements on the weight and on its support' bein utilized to operate the pump. v

Wth the above primary and other incidental objects in view the invention consists of the devices and parts and their equivalents, as hereinafter set forth. l

In the accompanying drawing the 4figure represents a side elevation of an oil-pump motor embodying the princi les of this invention and ap lie to a sig t-feed oil-pump such as is s own and described in Letters Specication of Letters Patent.

Patent to Wilber E. Richardson, No. 661,323,

In this drawing, 1 represents the oil-pump,

which may be of any desirable type and which is bolted or otherwise rigidly secured to asupporting means 2, such as the ca b of a locomotive or any other body, preferably receivin motion from the mechanlsm sup lied with oi by the pump, and 3 isthe sha t of said oilpump, which is capable of operating the pump mechanism When given sight oscillations. A sleeve 4 is fixed on the shaft Sand held rigid therewith by means of the nut 5, threade on said shaft and preferably binding the sleeve u on a shouldered squared portion of` the shat. A socket 6 is provided'on said sleeve, in which a lever-arm 7 is secured in any suitable manner.

An angular bracket 8 is 'ven rigid support with the moving body, eit er, as here shown, upon 4the pump 1 or in any other manner, and in a perforation of its projecting upper end, vwhich overhangs the lever-arm \7,- is loosely mounted an eyebolt 9, with its eye vportion lowermost and its nut 1,0 resting upon the upper surface of the bracket. y A coil-spring 11 has its hooked upper end engaged in the eye of the eyebolt 9 and its hooked lower end engaged in a perforated ear' 12 of the sleeve 13, which is mounted gage the lever-arm' 7, so that the ball-weight ma be ad'usted on the lever-arm nearer to or Iarther om the shaft 3.

The eyebolt 9 is adjusted by turning its nut 10 to a position where the coil-spring 11 normally supports the lever-arm 7 in a horizontal positlon, as shown. Then when the supporting means 2 is given quick vertical motions, such as the motlons of a locomotivecab when under way, the inertia of the ballweight 15 tends to prevent its partici ating in` suc'h movements and, as the pump ollows ICO ,30 l f shaft 3 moves vertically with the support.

- course and repeating, this operationguntil the the movements of the support, results in an oscillation of the shaft 3 and roduces the rIophe e weig t 15 with relation to l and operate the oil-pumpZ due to its springsupport, the s ring recoihng during the u ward course o the wei ht to lift it-above t e horizontal line of the ever-arm 7 and'then the gravity of the weight serving to lcarry it below suc horizontal line on its downward weight reaches its equilibrium.

When it is found that the motions of the supporting means are not suflicient to produce a desired operation of the oil-pump, the ball-weight 15 may be adjusted nearer to the shaft 3 b means of its set-screw 17, when the limited egree of movement of the supporting means with respect to the comparative immovable ball-welght correspondingly` increases the arc of movement ofthe lever-arm 7, and so increases the o eration of the pump. This action can best be ollowed by considering the ball-weight 15 a stationary fulcrum, upon which the lever-arm 7 swings as the lThe vertical movements of the shaft then clearly produce an oscillation ofl said shaft in its bearings, and the extent lof such oscillation depends upon the rangle of swing of the lever-arm, which is determined by the extent of vertical movement of the shaft. Now with a given vertical movement obvious that the angle of movement of the lever-arm, and therefore the degree ofoscillation of the shaft, will va inversely as-the distanceV between they bal -weight and the shaft. Consequently as vthe ball-weight is adjusted nearer -to -the shaft the an le of swing of the lever-arm enlarges, and t e are of oscillation of the shaft increases to give the pumping mechanisma greater out ut.

' W 'le the part 2 has been referre to herein as the movable support or body, it is obvious'that the bracket 8 and pump 1, which are intended to have a rigid connection therewith, `and therefore partake of the movements, may be considered as movable bodies or. movable supports,`and it is with the understanding that these terms movable su port7 and movable body are suflicient y oad to cover any body or support capable of movement orl designed to receive movement that they are employed in the following claims. Such terms are not intended to render the combinations incomplete without the resence of a moving englne-cab or other od by which the parts may be carried.
